We have used ConnectBooster for over 2 years now, and they have been an invaluable asset to our company. Before ConnectBooster, our accounting staff literally spent several DAYS per month, manually billing credit cards in QuickBooks, dealing with getting and updating cards, re-processing failed payments, and more. ConnectBooster has allowed us to fully automate that process and never have to touch a user's credit card. (PCI Compliance.. Done!)
